Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

People love holidays. Holidays are a major thing across the globe in every culture, religion, and country.

Schools, organizations, workplaces, and businesses curate a list of holidays to commemorate some festivals or events.

And when they arrive, people want to go to places and enjoy their days, relax and take a break from the everyday hustle and bustle.

So, if your business revolves around travel, you can leverage this craze for holidays to create solutions that can ease the life of travelers and cash out on these opportunities.

You can build a travel application and integrate it with a holiday API. This will enrich your app with accurate and updated holiday datasets every time you need them. 

But what exactly is this holiday API, and how beneficial is it?

Let’s talk about that, and then I’ll discuss some of the holiday APIs to build your applications. 

What do you mean by Holiday API?

Before we talk about holiday APIs, let’s shed some light on APIs first.

An Application Programming Interface or API is a software intermediary that allows an application to interact with another application.

Using an API, an app can access data to interact with outer software components, microservices, or operating systems. It is an interface or common ground for two applications to communicate with one another. It contains a set of functions that delivers a user response to the system and again sends that system’s response back to the user. 

Similarly, a holiday API is a service where you send a request to other systems programmatically about various holiday lists across the world and receive the programmatic data instantly.

Remembering the exact date for a holiday and maintaining the whole list is difficult. That’s why holiday APIs are developed to make the process easy. 

So, if you want a holiday in a particular country, you need to request it through code, and you will get accurate information.

Let’s take the example of Christmas. In many countries, it is declared a public holiday on December 25 every year. But, in some countries, it is declared on January 7 of every year, while other countries might not have it. 

If you are a multinational company, an airline industry, a stock market company, or others, you must be ready for the future holidays to prepare your organization for events. With a holiday API, you can even get the data of past holidays and observances. 

Example of holiday APIs: Suppose you want to plan your Christmas holidays, and the destination is the Bahamas. You can either book your flight from your preferred airline’s website, if available, or use an online travel service like Expedia. The latter aggregates data from multiple airline databases by interacting with airlines’ APIs. This way, you can book your seats and plan your holidays.

What are the features of Holiday APIs?


Security is a major concern for every app, site, or web service on the web. Since your application uses web services, hackers will try to fill up your API with millions of requests at a time and steal your information. Therefore, the holiday API you choose must have security features, like DDoS protection, to keep your information secure.


Modern businesses want to save time and effort in order to accelerate their processes and stay in the competition. This is why the API must offer decent performance. And to ensure that, you can check the feature list. You can also go for a free trial that most APIs offer these days or choose a free plan, if any.

Next, you must check how many milliseconds this API takes to give you the data you requested. The less time it takes, the more will be its performance. Ideally, whether you are making many requests at a time or just a single or double, an API must take a few milliseconds to get accurate data. 


API is a set of functions designed to produce correct data every time for your request. A holiday API must be updated and validated with changes in holidays so that no single user will miss the accurate data. If a holiday API offers precise date, time, and data, it can be good. 


An API is built by developers for developers. The holiday API must have good documentation so that a developer can read and comprehend its endpoints, methods, functions, and response options. 

Great documentation is also meant to be understandable by any consumer, even users with zero technical knowledge. Hence, it should have a good set of examples for each point or functionality. Good documentation also helps in integrating the API easily into your application. 

Use Cases of Holiday APIs

  • Sales and Marketing: Holiday APIs help sales and marketing-based businesses enhance their sales conversions by giving promotions and offers around the holidays. 
  • Data Science: You can enhance machine learning models with the holiday API by feeding in holiday information. 
  • Shipping and Logistics: With a good holiday API, you can increase the accuracy of the shipping estimates and timetables of the product delivery.
  • Email marketing: Send smarter emails to your users by including local holiday information via holiday API in your application.
  • Customer Experience: Communicate with your customers effectively by giving out the exact estimation about the service completion and fulfilling customer expectations. A holiday API also allows you to estimate the date and time, including the local holidays in the estimation.
  • Inventory Management: You can identify your demand catalysts to enhance inventory levels and supply chain efforts.  
  • Demand Forecasting: Increase the forecasting models for accurate demand predictions. 

Now, let’s check out the best holiday APIs.
